參數

  • fieldoffset
    型別：System. . :: . .Int64
    The index within the field from which to begin the read operation.
  • buffer
    型別：array<System. . :: . .Char> [] () [] []
    The buffer into which to read the stream of bytes.
  • bufferoffset
    型別：System. . :: . .Int32
    The index within the buffer where the write operation is to start.

傳回值

型別：System. . :: . .Int64
The number of characters read.

實作

IDataRecord. . :: . .GetChars(Int32, Int64, array<Char> [] () [] [], Int32, Int32)
